When updating from focal to jammy I found the following reproducible way to crash aptitude.
$ apt policy python3-chardet
python3-chardet:

python3-chardet and python3-six cannot currently upgrade on my machine due to bug 1958720. Updated packages come in all the time for jammy at the moment. When I hit + on the section of "Upgradable Packages" in aptitude I am thus currently always breaking packages. Aptitude calculates a way for me to resolve the problem, usually holding a couple of packages at their current version. I accept and then aptitude still shows 2 broken packages (this is a bug in itself, I guess). I can verify with b that the broken packages are python3-chardet and python3-six. I can hold both packages with : and move on and nothing bad happens. But if I don't do that and instead rely on aptitude resolving conflicts before installing by hitting g, then aptitude will reliably crash.
$ sudo aptitude
Uncaught exception: ../../src/ui.cc:1549: void auto_fix_broken(): Assertion "resman->resolver_exists()" failed. |
